Homemade Pellet Gun Flashlight.
This is my third attempt at making an effective CO2 Power Pellet Gun from a standard 2 AAA Battery Flashlight. This project will take about 3-4 hours to complete.

A Piece of Hard Rubber - The Plunger.

A small notepad.

Step 3: Finding The Right Flashlight/Torch

Most importantly, shop around for a better quality 2 AAA flashlight or torch. You can buy a cheap brand flashlight but you might be just wasting your time. You'll need to find a flashlight with 'O' Ring seals, a 'screw-off end cap', and check that the on/off switch is at the end of the unit. When you've finished your project, the flashlight must be completely airtight. I managed to find one with an on/off switch just a little smaller than the Schrader valve thread, which was perfect for the job.

Step 4: Start The Build

Once you've found your flashlight, remove the screw off end and drill out the existing on/off switch to suit the diameter of the Schrader valve. Trim and sand off all the rubber off the Schrader valve, leaving just the brass fitting. Find a suitable drill bit for the diameter of the valve thread. Use your notepad as padding in the vice so you don't scratch all the paint off your flashlight. Before gluing the valve, I trimmed off about 3-4mm off the end of the using a hacksaw. Glue the valve into place using your 2 pack epoxy and allow at least 24 hours for the glue to dry fully. Remember it needs to be airtight.
